Detailed Description

A "keeper" class for real-valued FFT transform objects.

Class implements "keeper" functionality for handling CDSPRealFFT objects. The allocated FFT objects are placed on the global static list of objects for future reuse instead of deallocation.

Constructor & Destructor Documentation

◆ CDSPRealFFTKeeper()

r8b::CDSPRealFFTKeeper::CDSPRealFFTKeeper ( const int LenBits )

Acquires FFT object with the specified block length.

Parameters

LenBits The length of FFT block (Nth power of 2), in the range [1; 30] inclusive, specifies the number of real values in a FFT block.
